Ole is a farmer in Minnesota.

He is in need of a new milk cow and hears about one for sale over in
Nordakota (that would be North Dakota for you non Scandhoovians out
there).
He drives to the Nordakota farm and looks over the cow. Ole reaches under to
see if she gives milk. When he grabs the teat and pulls ..the cow
farts.

Ole is very surprised. He looks at the farmer who is selling the cow,then
reaches under the cow to try again. He grabs another teat, pulls, and the cow farts again. Milk does come out however, so after some
discussion with the cow's owner, Ole decides to buy the cow and take her home.

When he gets back to Minnesota, he calls over his neighbor, Sven, and says,
"Hey, Sven, come and look at dis here new cow I yust bought. Pull her teat,
and see vat happens." Sven reaches under, pulls the teat and the cow farts.

Sven looks at Ole and says, "You bought dis here cow in Nordakota, didn't yah?" Ole is very suprised since he hadn't told Sven about his
trip. Ole replies, "Yah dats right. but, how did you know?

Sven says, "My wife is from Nordakota."
